HP- Cisco switch connectivity

Hi All,
I've got an HP Procurve 3500 Multilaer Switch, and we are configuring Inter VLAN routing in that. For a single switch Inter VLAN routing is OK but when we connect a Cisco 2960 switch, the VLAN information is not getting synchronized in the Cisco switch. Whereas if the PCs are in the default VLANs of both the switches they ping. And if the ports are put in VLAN 15 on each switch, they do not ping.
So it is clear that the VLAN information is not getting synchronized. I'm new to HP Procurve switches, please guide how to make them interoperable.
And also, HP-HP switch VLAN configuration.
Thank you.

Thanks Mike,
I can do trunking in cisco easily but its about trunking an HP and cisco
switch. Because terminology is changing and HP has some different way to
configure trunk (tagging). I just need to know the tagging concept in HP.

While I don't have much of a background in the HP Procurve line, I would
suggest the following.
1) A 802.1Q trunk should be established between your 2960 and the Pro
Curve.
2) Manually create your VLANs on your Cisco domain and in the HP domain.
(Cisco offers a feature called VTP which will help you by synchronizing
the VLAN's across to other Cisco switches in the VTP domain but I don't
think HP will "speak" the Cisco VTP language so it will require you to
manually create the VLAN on each side ot the trunk.
The dot 1 q trunk should however still pass traffic belonging to all
appropriate VLAN's as long as they exist on both sides of the trunk.
